GREENFIELD — An alleged heroin dealer has been charged after an alert citizen snapped photos of a suspected deal and called police.

Dwight Belisle, 46, of 8 Quincy St., Greenfield, pleaded innocent to charges of possession of heroin with intent to distribute, and possession of heroin as a subsequent offense, Tuesday in Greenfield District Court.

Belisle was arrested after a citizen saw him take cash from another man and give him a bag believed to contain drugs in front of a School Street residence, according to a report by Officer Justin Purinton.

The citizen took photos of the alleged dealer and gave them to Purinton, he wrote.

The officer didn’t even get back to his cruiser before he spotted the suspect.

Purinton wrote that he was on his way back to his patrol car when he saw Belisle about 100 yards away from the site of the alleged drug deal.

The officer approached Belisle and told him that he was an “exact match” for a suspected drug dealer, wrote Purinton. Belisle denied any involvement in drugs and said he was just out for a walk, according to the report.

Belisle is known to Greenfield Police as a suspected drug dealer, Purinton wrote.

After Belisle nervously shoved his hands deep into his pockets, Purinton frisked him for weapons, he wrote.

He found a large black folding knife and a small amount of marijuana in Belisle’s left pants pocket and noticed what felt like folded heroin bags in his right pocket, he wrote.

Searching the pocket, Purinton found six wax bags full of brown powder consistent with heroin, along with several crumpled bills from $1 to $20, wrote Purinton. A further search turned up three more bags in the band of Belisle’s ballcap, according to the report. All nine heroin packets were marked “300,” Purinton wrote.

Belisle was released on personal recognizance after paying $150 for a court appointed lawyer. He is set to return July 30 for a pretrial conference.
